The 2018 Toyota Trucks Sequoia sits in the full-size SUV world with the kind of body-on-frame toughness that appeals to owners who need passenger space, towing confidence, and genuine truck-based durability. Tire choice on this Sequoia starts with trim-specific fitment, because the vehicle uses either 275/65R18 or 275/55R20 radial tires depending on sub-model. That means the first step is confirming whether your truck is on 18-inch or 20-inch wheels before comparing tire options. For owners focused on real road use, everyday drivability, or a more aggressive truck look, choosing the correct size matters just as much as tread style and wheel compatibility.
Which Tire Size Is Right for The 2018 Toyota Trucks Sequoia
The 2018 Toyota Trucks Sequoia uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel diameter. Both are radial metric sizes, but one fits an 18-inch wheel and the other fits a 20-inch wheel, so confirming the actual wheel size on your Sequoia is the first step before comparing tire style, load capability, or appearance.
Fit(s): Limited, Platinum, SR5 w/Sport Pkg., and TRD Sport
Construction: Radial|Rim: 20 in
A 275/55R20 tire uses a 275-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2018 Toyota Trucks Sequoia, this size is tied to several higher-trim and sport-oriented sub-models, so it is important to match it to the correct wheel package rather than assume it applies across the board. Its shorter sidewall profile gives this fitment a more modern full-size SUV look than the 18-inch alternative. This is the size to evaluate if your Sequoia is equipped with factory-type 20-inch wheels or an equivalent 20-inch setup.
A 275/65R18 tire keeps the same 275-millimeter nominal width, but the 65-series profile pairs it with an 18-inch rim for a taller sidewall. This radial size applies to the 2018 Toyota Trucks Sequoia SR5 and suits buyers who want to stay with the correct 18-inch fitment before comparing tread design and wheel-width compatibility. In the available product selection, this size appears in BFGoodrich's All-Terrain T/A KO2 with raised white letter styling. It is the right starting point if your Sequoia runs 18-inch wheels and you want a truck-focused tire presentation.
Sub-model fitment matters on the 2018 Toyota Trucks Sequoia because tire size changes with wheel package. Most covered trims use 275/55R20, while the SR5 uses 275/65R18, so identifying the exact sub-model helps prevent a mismatch between tire and wheel diameter.

2018 Toyota Trucks Sequoia Limited
The 2018 Toyota Trucks Sequoia Limited uses the 275/55R20 radial fitment. That makes wheel confirmation especially important if the truck has been changed from its original setup, since a 20-inch tire choice needs to stay matched to the correct rim diameter.
The 2018 Toyota Trucks Sequoia Platinum also uses 275/55R20 radial tires. Tire selection here centers on staying with the proper 20-inch metric size and checking the actual wheel setup before comparing tread style or replacing worn tires.
The 2018 Toyota Trucks Sequoia SR5 uses the 275/65R18 radial size rather than the 20-inch fitment found on several other trims. That means replacement shopping should begin with the 18-inch wheel package and then move into choices such as all-terrain styling and rim-width compatibility.
The 2018 Toyota Trucks Sequoia SR5 w/Sport Pkg. uses the 275/55R20 radial fitment. Even though it shares the same size as several other sub-models, confirming that the truck still has the correct 20-inch wheels is the key first step before selecting replacements.
The 2018 Toyota Trucks Sequoia TRD Sport uses 275/55R20 radial tires. Buyers replacing tires on this sub-model should focus on maintaining the proper 20-inch size and verifying wheel and clearance details if any suspension or wheel changes have been made.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2018 Toyota Trucks Sequoia?
The 2018 Toyota Trucks Sequoia uses two tire sizes: 275/55R20 and 275/65R18. The correct size depends on the sub-model. Limited, Platinum, SR5 w/Sport Pkg., and TRD Sport use 275/55R20, while the SR5 uses 275/65R18.
That makes trim and wheel confirmation more important than simply shopping by model name. A Sequoia with 18-inch wheels needs the 275/65R18 fitment, while a Sequoia with 20-inch wheels needs 275/55R20. If the truck has aftermarket wheels or a previous owner changed the setup, check the actual wheel diameter before ordering tires.
What size rim does a 2018 Toyota Trucks Sequoia use?
A 2018 Toyota Trucks Sequoia uses either an 18-inch or 20-inch rim, depending on sub-model. The 275/65R18 tire fits an 18-inch wheel, and the 275/55R20 tire fits a 20-inch wheel.
Rim diameter is the first fitment detail to verify because the two Sequoia tire sizes are not interchangeable across those wheel sizes. Tire width and profile also need to stay appropriate for the wheel. If the truck has replacement wheels, confirm both the diameter and the wheel width before comparing tire options.
Do all 2018 Toyota Trucks Sequoia sub-models use the same tire size?
No. The 2018 Toyota Trucks Sequoia uses different tire sizes across its sub-model range. The SR5 uses 275/65R18, while the Limited, Platinum, SR5 w/Sport Pkg., and TRD Sport use 275/55R20.
That difference usually follows the wheel package, so choosing by sub-model is the safest starting point. It is still smart to inspect the truck itself, especially if it has changed hands or received wheel upgrades. Matching the tire to the actual wheel diameter helps avoid ordering a tire that cannot be mounted on the vehicle's current rims.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Toyota Trucks Sequoia?
Start with the correct trim-specific size: 275/65R18 for the SR5 or 275/55R20 for the Limited, Platinum, SR5 w/Sport Pkg., and TRD Sport. Both are radial metric sizes, so the main decision begins with matching the tire to the wheel diameter already on the truck.
After size, think about how the Sequoia is actually used. Daily highway driving, towing, and rougher surface use may point you toward different tread styles within the correct fitment. Wheel width, load capacity, sidewall style, and the truck's current suspension and wheel setup should all be checked before making a final selection.
What sidewall styles are available for 2018 Toyota Trucks Sequoia tires?
Among the currently available Sequoia product options, the 275/65R18 size is offered with an RWL sidewall. That means raised white letter styling, a look many truck and SUV owners choose for a more traditional off-road or all-terrain appearance.
Sidewall style does not change the need to stay with the correct tire size and wheel diameter, but it can noticeably affect how the vehicle looks. If appearance matters, compare the sidewall treatment alongside the tread design and tire series. On a full-size SUV like the Sequoia, that visual choice can be almost as noticeable as the wheel itself.
What tire series are available for the 2018 Toyota Trucks Sequoia?
The currently available 275/65R18 Sequoia product offering includes the BFGoodrich All-Terrain T/A KO2 series. That places the available choice in a truck-oriented all-terrain category rather than a smooth-sidewall touring presentation.
Series matters because it helps describe the tire's character and intended look. For a Sequoia owner, that can mean choosing between a more rugged visual style and a tire setup that matches how the SUV is driven. Even within the correct size, compare the series with your wheel package, ride expectations, and use on pavement or mixed surfaces.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Toyota Trucks Sequoia restoration or preservation project?
Yes. Even on a modern full-size SUV like the 2018 Toyota Trucks Sequoia, correct tire fitment helps preserve the intended stance, wheel proportion, and overall presentation of the vehicle. The main concern is using the right trim-specific size, either 275/65R18 or 275/55R20.
Appearance can change noticeably when the sidewall profile or wheel diameter no longer matches the original style of the sub-model. A preservation-minded owner should confirm the truck's trim, wheel size, and current setup before replacing tires. If exact as-delivered appearance matters, factory literature or model-specific reference material is worth consulting before making a change.
Which tire should I choose for a period-style 2018 Toyota Trucks Sequoia?
A period-style choice for a 2018 Toyota Trucks Sequoia starts with the same size the sub-model used: 275/65R18 for SR5 or 275/55R20 for Limited, Platinum, SR5 w/Sport Pkg., and TRD Sport. Staying with the proper wheel diameter does more for the vehicle's appearance than changing tread style alone.
From there, sidewall and series become the visible details to compare. On the available 275/65R18 option, raised white letter styling and the All-Terrain T/A KO2 series create a more truck-oriented look. Buyers focused on a clean factory-inspired presentation should compare the tire's visual character with the Sequoia's trim and wheel package before deciding.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Toyota Trucks Sequoia?
Yes. Wheel changes, suspension lifts or lowering, spacer use, and other modifications can all affect tire fitment on a 2018 Toyota Trucks Sequoia. Even when the tire size matches the original trim, the actual wheel width, offset, and clearance at the fender and suspension still need to be considered.
That matters most on a Sequoia that no longer has its original wheels. An 18-inch SR5 setup and a 20-inch sport-oriented setup are not the same starting point. Before mounting replacement tires, inspect for rubbing marks, measure the wheel diameter already on the truck, and make sure the tire suits the current configuration rather than the badge alone.
What should I inspect before driving a 2018 Toyota Trucks Sequoia on new tires?
Before regular road use, inspect tire pressure, lug nut torque, valve stems, tread and sidewall condition, and clearance around the front suspension, inner fenders, and rear wheel openings. On a 2018 Toyota Trucks Sequoia, it is also important to confirm that the installed tire size matches the truck's 18-inch or 20-inch wheel setup.
A short test drive can reveal rubbing, vibration, or pull that is easier to correct early. Recheck air pressure after the first few drives and watch for uneven wear as the tires settle into service. If the Sequoia has alignment issues, worn suspension parts, or non-stock wheels, those problems can show up quickly with a fresh set of tires.
How often should tires on a 2018 Toyota Trucks Sequoia be inspected?
Tires on a 2018 Toyota Trucks Sequoia should be inspected regularly, not only when they look worn. Monthly pressure checks are a smart routine, and visual inspections should include tread depth, uneven wear, sidewall cracking, cuts, punctures, and any signs of bulging or slow air loss.
A full-size SUV places real demands on its tires, so catching problems early matters for both ride quality and road use. Inspect more often before longer trips, towing, or seasonal travel. It also helps to look at the wheel and tire combination together, since damage, curb impact, or a mismatched setup can affect fitment just as much as tire wear.
